The regeneration director overseeing Grenfell Tower’s refurbishment has told the inquiry into 2017’s disaster he had no concerns main contractor Rydon’s successful £9.2m bid was “unrealistically low”, even after another £800,000 in savings was sought.

Peter Maddison also told the inquiry into the fire, which claimed 72 lives, he was sorry for the “devastating impact” that a project he believed should have been a “straightforward” design and build contract had on so many lives.
